Investigation of solar energy potential on inclined surfaces

Abstract

Solar energy is considered environmentally friendly because the sun is a natural energy source that does not require the fossil fuels and the associated air emissions. The solar energy data in the sloped surfaces are essential for the design of solar energy applications. The values of the daily average total solar radiation on a horizontal plane are nearly available. However, the radiation values on inclined surfaces are generally not available. This paper deals with the analysis to f-chart method of solar energy utilization for horizontal surface and various tilt angles of solar panel such as optimum tilt angle, seasonal, summer-winter applications. The values of the highest H T and f are the surface with optimum tilt angle, seasonal, summer-winter, s 5 u 6 158, s 5 u, s 5 u-158, s 5 u 1 158 and horizontal, respectively. In comparison of the surfaces of the optimum tilt angles and horizontal, it is seen that the increment in the annual fractions of the surface with the optimum tilt angle is 21%. The yearly total values of the H T on the surface of the optimum tilt angle and horizontal are found as 6719.3 and 5602.2 MJ/m 2 , respectively.

“…Approximately, 80% of the world energy comes from fossil fuels and it tends to increase (ALMARSHOUD and ADAM 2018;BELLOS and TZIVANIDIS, 2018). The use of renewable energies will balance the effects on the relationship between economic development and environmental problems, once as much development is needed, more energy is used and more environmental problems will be faced (BAKIRCI 2017;CHIRINO et al 2018;ERRAISSI et al 2018).…”
